Part II — Monitoring MSSQL on Windows Server: A Guide to Maximizing Database Performance

Here’s how to perform this comprehensive monitoring:


  1. Enable SQL Server Agent: Activate the SQL Server Agent for interaction with external collectors such as Prometheus.
  2. Install Prometheus Windows Exporter: Download and install the Prometheus Windows Exporter from GitHub.
  3. Set Up Prometheus Scraper/Database: Install Prometheus on your monitoring server/computer and configure the scraper.
  4. Access Prometheus Server and Add Targets: Access the Prometheus server through a browser and add a new target.
  5. Query SQL Server Processes: Execute the necessary query to query SQL Server processes.
  6. Install Grafana and Connect to Prometheus: Install Grafana, connect it to the Prometheus server, and visualize the data.

In our previous article, you can find information on how to perform monitoring on a Windows server.

  1. Enable SQL Server Agent in SSMS:
  • To allow external collectors (e.g., Prometheus) to query the SQL Server engine, enable the SQL Server Agent.
  • SQL Server Agent
  • Change the startup type of the SQL Server Agent service to “Automatic” so that it starts automatically upon system startup.

Services / Automatic
2.Install Prometheus Windows Exporter:
  • Download  the Prometheus Windows Exporter from GitHub.
  • Use the installer found in the “Assets” section to install the exporter.
  • You can use the default Windows node exporter provided by Prometheus, which includes basic SQL Server metrics. No additional exporter installation is needed.
  • Install the exporter using the MSI installer.
  • After installation, the binary will be located in theC:\Program Files\windows_exporterfolder.
  • If a process/task named “windows_exporter” is running, terminate it, as we will need to manually start the exporter with some additional flags.
  • Manually run the exporter with the following command to fetch SQL Server statistics:
C:\Program Files\windows_exporter\windows_exporter.exe --collectors. Enabled="cpu,cs,logical_disk,net,os,service,system,textfile,mssql"
  • Access http://localhost:9182/metrics in your browser to view available metrics.
  • To make the changes persistent, add the following settings to the registry:
"C:\Program Files\windows_exporter\windows_exporter.exe" --collectors.enabled="cpu,cs,logical_disk,net,os,service,system,textfile,mssql" --log.format logger:eventlog?name=windows_exporter

Search for “regedit” in the Start menu.


Open regedit.

HKEY_LOCAL_MACHONE/SYSTEM/Current ControlSet/Services/windows_exporter

in the opened window and make the registry changes we provided above to the ‘ImagePath’.


3-  Install Prometheus and Configure the Scraper:

  • Download the latest version of Prometheus from ,
  • Extract the downloaded .tgz file to an appropriate folder.
  • Run the binary file named prometheus.exelocated in the extracted folder.
  • There will be a file named prometheus.yamlin the directory where Prometheus is installed.
  • Open this file with a text editor. In thestatic_configssection, add the IP address of the Windows server you want to add as a target.


 - job_name: "MSSQL_SERVER"

# metrics_path defaults to '/metrics'
# scheme defaults to 'http'.

- targets: ["MSSQLSERVERIP:9182"]
  • Replace “MSSQLSERVERIP” with the actual IP address of your Windows server.
  • Save and close the file.

4.Access the Prometheus Server and Add Targets:

  • Open a browser and go to localhost:9090
  • In the Status -> Targets tab, make sure the target at MSSQLSERVERIP:9182/metrics is UP.
Prometheus — UP
Prometheus — UP
5. Query SQL Server Processes Through Prometheus:
  • Tarayıcınızı açın ve Prometheus sunucusuna gidin. Varsayılan olarak localhost:9090 .Open your browser and go to the Prometheus server. By default, it’s localhost:9090
  • Click on the “Console” tab in the upper left corner. This is where you can run PromQL queries.
  • Query SQL Server processes by entering the following query:
rate(windows_mssql_sqlstats_batch_requests[30s]) * 60
sql sorgu
sql sorgu

6.Install Grafana and Connect to Prometheus:

  • Install Grafana and access the interface at localhost:3000.
  • Use the “Import” option to add the MSSQL Windows Exporter Dashboard theme. Enter ‘15024’ as the ID in the “Import via” section and proceed with “Load.”
  • In the “Data Sources” section, add the “Prometheus” data source and “Import” it.
  • Now, you can visually examine SQL Server statistics in the added dashboard.
